纤维增强塑料 - 成型化合物和预浸料 - 测定每单位面积的质量

[中文适用范围]： 本文件规定了单位面积质量的测定方法。 它还规定了测定模塑料和预浸料单位面积纤维质量的五种方法（方法A至方法E）。 五种方法如下： ——方法A：索氏提取； ——方法B：浸入烧杯中的溶剂中提取； ——方法C：失量灼烧分解； ——方法D：湿式燃烧萃取； ——方法E：计算法。 本文件适用于以下类型的材料： ——模塑料和预浸渍单向片材、带材、织物和垫子； ——使用任何类型的增强材料（芳纶、碳、玻璃等）和任何类型的基体（热固性或热塑性）的预浸料。 通常，增强纤维涂有浆料或饰面。 这些通常与树脂溶解，因此包含在树脂成分中。 本文件不适用于以下类型的预浸料： ——含有可溶于（或部分可溶于）用于溶解树脂的溶剂的增强材料的预浸料。 [外文原描述]： This document specifies a method for the determination of the mass per unit area. It also specifies five methods (Method A to Method E) for the determination of the fibre mass per unit area of moulding compounds and prepregs. The five methods are as follows: — Method A: Extraction by Soxhlet; — Method B: Extraction by immersion in solvent in a beaker; — Method C: Decomposition by loss ignition; — Method D: Extraction by wet combustion; — Method E: Method by calculation. This document is applicable to the following types of materials: — moulding compound and preimpregnated unidirectional sheet, tape, fabric and mats; — prepregs in which any type of reinforcement (aramid, carbon, glass, etc.) and any type of matrix (thermosetting or thermoplastic) has been used. Typically, reinforcement fibres are coated with sizing or finishes. These normally dissolve with the resin and are, therefore, included in the resin content. This document is not applicable to the following types of prepregs: — those containing reinforcements which are soluble (or partly soluble) in the solvents used to dissolve the resin.
